Improvement in treating hair for weaving



UNITED STATES PATENT OFFICE.

JOHN GLEDHILL, OF NEW YORK, N. Y.

llVlPROVEMENT I'N TREATING HAIR FOR WEAVING.

Specification forming part of Letters Patent No. 10,555, dated February 21, 1854. E

To all whom, t may concern,.-

Be it known that I, JOHN GLEDH1LL,0E the city, county, and State of New York, have invented a new and useful Improvementin the Treatment of Hair for leaving into Cloth;

- and I do hereby declare that the following isa full, clear-,and exact'description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a longitudinal View, on an eX- ag'gerated scale, of part of a hair, exhibiting the effect of the treatment upon the end. Fig. 2 is a similar view with the hair in what I term the serving-hook. Fig. 3 is a transverse View of the hair in the serving-hook.

Similar letters of reference indicate corresponding parts in each of the several figures.

rlhe nature ot' my invention consists in raising a bulb or knob on either side of the hair by heat or chemical agency, for the purpose of preventing tlieharslipping from the notched hook or other device by which it is wholly or partly drawn out from the bunch and served to the loom, and insuring its being properly caught and held as long as is necessary.

The property possessed by hair of forming a bulb or knob when singed by heat or submitted to the action of certain chemical agents is well known, and therefore needs no explanation. I consider that the method of raising the bulb or knob best suited for this purpose is to apply the ends of a bunch of hair to the surface of a heated metal plate, then all will be singed nearly or quite alike; but as there may be many other ways Which would answer the purpose quite or nearly as well I do not consider it necessary to limit myself to the use of this particular method.

The utility of the invention may be understood by reference to the drawings, in which A, Figs. 2 and 3, represents the end of the serving-hook, and d the notch which receives the hair and which holds it while the hook moves in such a direction as to draw it from the bunch. 'lhe hook catches Athe hair b a short distance behind its bulb c and moves` toward the bulb, which prevents its slipping off and causes the hair to be carried by the hook. The bulb forms no impediment to the escape of the hair from the hook at the proper time, as the hair is drawn from the notch to- Ward the points of the hook. Vithout such a bulb or knob so simple a contrivance as a notched hook could not be depended upon ro effect the desired object, and it would `be almost impossible to devise any means which would seize the hair and also relinquish it wit-h suiiicient readiness without the bulb.

- WVhat I claim as my invention, and desire to secure by Letters Patent, is-

Preparing hair for being woven into Cloth by raising a'bulb or knob at either end, substantially as shown and described, whether by the action of heat or by any chemical agent, whereby the hair is made capable ot' being readily seized and as readily relinquished by a device which serves it to the operating parts of the loom.
